Home Network :: Netgear Router WNR 2000 V3 - Cannot Access Internet When Security Password Chosen?

I just bought a Netgear Router WNR 2000 v3 and installed it. I got inside the router and could set up a Network Name and security key. However, I can not access the internet when I chose a security password using WPA 2, WPA-PSK + WPA 2 PSK, or WPA/WPA 2. It only accesses the internet when I chose None.( no secured ).At this time, my network is unsecured because there isn't way I can access the internet when I create a security key using the 3 options the router offers.

Note : I have tried the 3 security options creating a key number and my computer connect to the wireless network but don't access the internet. It only access the internet when I select None ( no secured )
